Using Composer, add to composer.json:

    "require": {
        "matthiasnoback/microsoft-translator": "dev-master"

Then using the Composer binary:

php composer.phar install


This library uses the Buzz browser to make calls to the Microsoft Translator V2 API.

You need to obtain a Microsoft Azure Cognitive Services subscription Key. This can be used to instantiate the AzureTokenProvider:


use Buzz\Browser;
use MatthiasNoback\MicrosoftOAuth\AzureTokenProvider;
use MatthiasNoback\MicrosoftTranslator\MicrosoftTranslator;

$browser = new Browser();


$accessTokenProvider = new AzureTokenProvider($browser, $azureKey);

$translator = new MicrosoftTranslator($browser, $accessTokenProvider);

Azure DataMarket token usage [deprecated]

You need to register your application at the Azure DataMarket and thereby retrieve a "client id" and a "client secret". These can be used to instantiate the AccessTokenProvider (deprecated) on which the MicrosoftTranslator depends:


use Buzz\Browser;
use MatthiasNoback\MicrosoftOAuth\AccessTokenProvider;
use MatthiasNoback\MicrosoftTranslator\MicrosoftTranslator;

$browser = new Browser();

$clientId = '[YOUR-CLIENT-ID]';
$clientSecret = '[YOUR-CLIENT-SECRET]';

$accessTokenProvider = new AccessTokenProvider($browser, $clientId, $clientSecret);

$translator = new MicrosoftTranslator($browser, $accessTokenProvider);

Optional: enable the access token cache

Each call to the translator service is preceded by a call to Microsoft's OAuth server. Each access token however, may be cached for 10 minutes, so you should also use the built-in AccessTokenCache:


use MatthiasNoback\MicrosoftOAuth\AccessTokenCache;
use Doctrine\Common\Cache\ArrayCache;

$cache = new ArrayCache();
$accessTokenCache = new AccessTokenCache($cache);

The actual cache provider can be anything, as long as it implements the Cache interface from the Doctrine Common library.

Making calls

Translate a string

$translatedString = $translator->translate('This is a test', 'nl', 'en');

// $translatedString will be 'Dit is een test', which is Dutch for...

Translate a string and get multiple translations

$matches = $translator->getTranslations('This is a test', 'nl', 'en');

foreach ($matches as $match) {
    // $match is an instance of MatthiasNoback\MicrosoftTranslator\ApiCall\TranslationMatch
    $degree = $match->getDegree();
    $translatedText = $match->getTranslatedText();

Detect the language of a string

$text = 'This is a test';

$detectedLanguage = $translator->detect($text);

// $detectedLanguage will be 'en'

Get a spoken version of a string

$text = 'My name is Matthias';

$spoken = $translator->speak($text, 'en', 'audio/mp3', 'MaxQuality');

// $spoken will be the raw MP3 data, which you can save for instance as a file


Take a look at the tests to find out what else you can do with the API.

To fully enable the test suite, you need to copy phpunit.xml.dist to phpunit.xml and replace the placeholder values with their real values (i.e. client id, client secret and a location for storing spoken text files).

Related projects

There is a MicrosoftTranslatorBundle which makes the Microsoft translator available in a Symfony2 project.

There is also a MicrosoftTranslatorServiceProvider which registers the Microsoft translator and related services to a Silex application.


There are some more calls to be implemented, and also some more tests to be added.
